If you install the Intel® PRO/100 VE desktop adapter into a CNR (Communications and Network Riser) slot while the power cord is still attached to the computer, you may create a condition in which the adapter cannot communicate with the network. The link light will light if a network connection is active and the adapter will appear to be fully functional to the system, but you will not be able to send or receive packets. In Windows* 2000, if you position the mouse over the network icon in the tray, it will indicate that no cable is attached.

Anytime a power cord is plugged into the computer, standby power is available and the CNR slot is powered on even when the computer is powered off. Inserting the PRO/100 VE adapter into the CNR slot while the slot is powered on is what causes this symptom. You must always remove the power cord before installing the PRO/100 VE into the CNR slot.

For safety reasons, and to avoid damaging the computer, you should never install any expansion adapter while a live power cord is plugged in. However, if you have inadvertently installed your PRO/100 VE while the power cord was attached and created this symptom, you can resolve it by following this procedure.

Shut down the computer and remove the power cord, then remove the PRO/100 VE from the CNR slot. Then plug the power cord back into the computer for several seconds. Remove the cord again, wait several seconds, then reinstall the PRO/100 VE. Re-insert the power cord and power the machine back on.

This problem description only applies to the removable Intel PRO/100 VE desktop adapter that plugs into a CNR slot on the motherboard and is sold separately. For Intel adapters that are built into the computer, please contact the computer or motherboard manufacturer for adapter related networking issues.
